Large Lot Subdivision

Project Summary: Proposal to amend the Teton County Land Development Regulations (LDRs) pursuant to Wyoming State Statute 18-5-316, Requirements for Large Acreage Subdivision Permits. This would remove the blanket exemption for the subdivision of parcels larger than 35 acres, creating new submission and analysis requirements in order to increase transparency on the condition, development potential, and accessibility of subdivided parcels.

  • These changes include standards for the following categories:
    • Map of survey
    • Purchasing documents
    • Sewage 
    • Utility connection
    • Water supply
    • Ingress and egress
    • Financial resources
    • Water rights
    • Covenants
    • Land conditions and conservation
    • Mineral rights

Parcels remain exempt through the Exempt Land Division Process if:  the subdivision includes ten or fewer new parcels and the parent parcel was platted on or before July 1, 2008, or the parcels are over 140 acres.
